classes/image_live: allow different filesystems to be used for live images

The idea is copied from commit df0b217f3df2c36a32e5c4afaec36a28bfc77bbb:
[ classes/image_vm: allow different filesystems to be used for VM images ]

The same logic should apply to image_live.bbclass, to allow other
filesystems to be used vs just ext4. The default value of ext4 is kept
so there is no functional change unless LIVE_ROOTFS_TYPE is set in the
inherting recipe.
